SAN ANTONIO (AP) Tony Parker had 17 points and 11 assists and Tim Duncan added 19 points to help the San Antonio Spurs beat the Memphis Grizzlies 103-82 on Wednesday night, extending their home winning streak to 13 games.

The Spurs shot 58 percent from the field in becoming just the third team to score more than 100 points against the Grizzlies.Boris Diaw added 14, Kawhi Leonard 13 and Tiago Splitter 10 for San Antonio (30-11).
